Decision Block - correct answer ✔The diamond-shaped block used for
YES/NO questions. These blocks have two outputs: 1 (for yes) and 2 (for no).
Flow Chart - correct answer ✔A graphical representation of the progress of a
system for the definition, analysis, or solution of a data-processing or
manufacturing problem.
Flow Lines - correct answer ✔The connecting line or arrow between symbols
on a flow chart.
Input/Output Block - correct answer ✔A function that makes information
available for processing or that records processed information.
Interface - correct answer ✔The connection between the computer and the
control system.
Iterative - correct answer ✔Process flow that may repeat or skip steps until
some condition is satisfied.
,Open Loop - correct answer ✔A control system that has no means for
comparing the output with input for control purposes. An open-loop system
often requires human intervention.
Potentiometer - correct answer ✔A variable resistor.
Process Block - correct answer ✔Part of a flowchart that tells the program
what action to take.
Schematic - correct answer ✔A diagram that uses special symbols in place
of actual pictures. In a wiring schematic, for example, a squiggly line is used
to represent a resistor.

the value of another variable.
FMS - correct answer ✔Flexible Manufacturing System. A flexible group of
CNC machine tools that are highly automated and integrated capable of
producing a family of parts.
Independent Variable - correct answer ✔The controlling factor between
variables, on which the value of the other variable depends.
JIT - correct answer ✔Just in Time. A system that eliminates work-in-process
(WIP) inventory by scheduling arrival of parts and assemblies for an operation
